1. Today my mother gave me 50 yuan to buy fruits and vegetables. I bought a bag of apples, 6 yuan money, a catty of cucumbers, a catty of 2 yuan, a catty of shrimp 28 yuan and a bag of strawberries and 5 yuan. The salesman asked me how much it was. I listed in my mind: 50-6-2-28-5 = 4 1 (yuan), and quickly said that I want 4 1 yuan. The salesman then asked, "How much do I give you?" I said I would get my 9 yuan money back. The salesman praised me as great, and I was very happy. When I got home, I gave the rest of the money to my mother, and her mother smiled with satisfaction.

Today, my family packed three large plates of jiaozi, and I counted 68 in one pot. At this time, my father asked me, "If there are six people eating, how much will each person get?" I wrote a formula: 3×68÷6=, I think: First, how many coquettes are there? I listed 3×68 vertically and calculated that there are 204 * *. It is very easy to know the total number of hinges and distribute them to six people on average, 204÷6=, and the calculation result of column sag is 34. I told dad to eat 34 jiaozi each. It turns out that life is inseparable from mathematics.

Today, my family went to KFC in Longgang for a family meal. When we get there, people are always crowded. We finally ordered good food and found a seat to sit down. Here comes the food. This is a sumptuous set meal. There are 12 drumsticks in it. I thought: how to divide it equally? Then I remembered the division of 12÷3=4. We each have four drumsticks. Later, I ate my mother's 1 chicken leg and my aunt's two chicken legs. My aunt said, "You can't eat this for free. I ask you, how much did you eat? " How many more servings do you have to eat before you can finish them all? "I thought about it and replied," I ate 7/ 12, and then I ate 5/ 12. I ate all of it. "Fortunately, I learned the knowledge of fractions and can answer the questions correctly.
